:SIGN ATURE-DELIVERY MECHANTSM. I

Application filed November To all whom it may concern:

Be it known that I, Howano M. Beneath, a citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Signature- Delivery Mechanism, of which the following is a specification.

My invention comprises means for accurately timing the engagement of the signatures by the packer delivery fingers so that the signatures may he carried into the packers with the minimum amount of disturbance, said time adjusting means being capable of operation while the machine is running.

A practical embodiment of my invention is represented in the accompanying drawings,in which Fig. 1 represents so much of a signature delivery mechanism in end elevation as will illustrate my invention.

Fig. 2 represents a longitudinal vert cal; section taken in the planes of the line Il-fll, of Fig. 1. i

Fig. 3 represents a transverse detail section taken in the plane of the hne III-III of Fig. 2.

'The pair of coacting signature dellvery rolls 1, 2 are suitably mounted in the side frames 3, 4 of the machine. The packer trough comprises the usual bottom and paiis of sides {3, 7, which sides extend in opposite directions from the members 8, 9 of the chute which receives the signatures from the delivery rolls 1, 2. V

The packer fingers 10 uprise from their slide 11, which slide is rcciprocated by the following means:

The drive shaft 12 is rotatably mounted in the side frames 3, 4. A wide faced spiral gear 13 is mounted on and slidably interlocked with the drive shaft 1, which spiral gear meshes at all times with a spiral gear 14, fast on a cross shaft 15, su1tably mounted in the side frames 3, 4. A crank disc 16 is also fast on the cross shaft 15, to which crank disc one end of a connecting rod 17 is adjustably secured, the other end of which rod is attached to a segmental gear 18, whereby the rotary movement of the disc 16 imparts a rocking movement to the segmental gear 18.

The segmental gear 18 meshes with a gear 19, fast on a cross shaft 20, rotatably mount- 9, 1923. Serial in). 673,773.

ed in the side frames 3, 4, which cross shaft carries the gears 21, 22, which meshwith the toothed racks 23, 24, carried by the packer finger slide 11.

The bottom 5 of the packer is cut-away, as shown at 25, to permit the reciprocating movement of the packer fingers 10.

It is extremely important that the move ment of these packer fingers 10 be accurately timed with respect to the delivery of the signatures so that the packer fingers will be caused to engage the signatures at the proper instant to permit the signatures to be forced one end of which screw shaft is provided,

with a screw 27 in engagement with a fixed nut 28, secure-d to the side frame 4. A yoke 29 is loosely mounted on the screw shaft 26 which yoke engages the hub of the wide faced spiral gear 13, to move the gear laterally along the driveshaft 12 as the screw shaft 26 is turned in one or the other direc- "'tion. The screw shaft 26 is provided with a suitable hand wheel 32 for operating it.

The signature delivery rolls 1, 2 are driven from the drive shaft. 12, through the train of gears 33, 34, 35, 36, 37, 38, 39.

-From the above description it will be seen that the relative position of the packer fingers with respect to the drive shaft may be varied by the lateral movement of the spiral gear 13 with respect to the spiral gear 14, due to the turning of the screw shaft 26, so that the position of the packer fingers with respect to the position of the signature delivered from the rolls 1, 2, intothe chute 8, 9 may be adjusted to cause the packer fingers to engage the signatureat the proper instant, thus causing a minimum disturbance of the signature as it is forced into its packer. It will also be seen that this adjustment may be made while the machine is running, when the need of adjustment can be readily ascertained.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention; hence, I do not wish to be limited to the particular embodiment herein shown and described, but what I claim is i 1. In a packer signature delivery, the packer fingers, means for reciprocating them, and manually operated means for timing the fingers with respect to the delivery of the signatures while the machine is; running.

2. In a packer signature delivery, the packer fingers, means for reciprocating them, and manually operated means for timing the fingers with respect to the delivery of the signatures, comprising two meshing spiral gears in the finger reciprocating means, one of said gears being movable laterally with respect to the other.

3. In a packer signature delivery, the packer fingers, means for reciprocating them, and manually operated means for timing the fingers with respect to the delivery of the signatures, comprising two meshing spiral gears in the finger reciprocating means, their shafts, one of said gears being slidably interlocked with its shaft, and a longitudinally movable shaft carrying a yoke engaging the last named gear, whereby the longitudinal movement of the shaft will cause the yoke to move the last named gear laterally with respect to the other gear.

4. In a packer signature delivery, the packer fingers, means for reciprocating them, manually operated means for timing the fingers with respect to the delivery of the signatures, comprising two meshing spiral gears in the finger reciprocating means, their shafts, one of said gears being slidably interlocked with its shaft, and a screw shaft carrying a yoke engaging the last named gear whereby the turning movement of the screw shaft will move the yoke engaged gear laterally with respect to the other gear.

I 5. In a packersignature delivery, a main drive shaft, a pair of coacting signature delivery rolls driven thereby, packer fingers reciprocated by said drive shaft, and manually operated means for timing the contact of the fingers with the signature being delivered by said rolls comprising a device for changing the relative position of the packer fingers with respect to the drive shaft.

6. In a packer signature delivery, a main drive shaft, a pair of coacting signature delivery rolls driven thereby, packer fingers reciprocated by said drive shaft, and manually operated means for timing the contact of the fingers with the signature being delivered by said rolls while the machine is running comprising a device for changing the relative posit-ion of the packer fingers with respect to the drive shaft.

7. In a packer signature delivery, a main drive shaft, a pair of coacting signature delivery rolls having a geared connection therewith, reciprocating packer fingers also having a geared connection with-the drive shaft, and manually operated means for timing the contact of the fingers with the signature being delivered by said rolls comprising a device for changing the relative position of one gear of the chain of gears, leading to the packer fingers, with respect to its meshing gear.

8. In a packer signature delivery, a main drive shaft, a pair of coacting signature dclivery rolls having a geared connection therewith, reciprocating packer fingers also having a geared connection with the drive shaft, and manually operated means for timing the cont-act of the fingers with the signature being delivered by said rolls while the machine is running comprising a device for changing the relative position of one gear of the chain of gears, leading to the packer fingers, with respect to its meshing gear.

In testimony, that I claim the foregoing as my invention, I have signed my name this 7th day of November, 1923.

HOWARD M. BARBER.
